[0032] Embodiment 2

[0033] When training the pilot's eyes, the utility model uses the simulated flight scene developed by the flight simulation basic platform combined with virtual reality technology, customizes the direction of the eye-simulated flight scene, uses virtual reality simulation environment, develops simulated scenes based on virtual reality technology in multiple weather conditions, and uses real night aircraft, scenes, light, etc. to provide real vision and experience. It is used to assist in testing, and with the help of physical testing equipment, it checks the changes in vision, diopter, and the above optical quality evaluation indicators before and after the simulated flight test.

[0034] The basic functions of the software are divided into multiple modules

[0035] 1. Flight control simulation, take-off, climb, turn, level flight, descent and landing.

[0036] (1) Simulated takeoff: In a virtual environment, the subjects control the takeoff process of the aircraft and reasonably configure the various parameters required for takeoff, such as throttle control and flight speed.

[0037] (2) Simulated climb: After completing the takeoff phase, the test subject needs to guide the aircraft to a predetermined flight altitude. During this process, the test subject needs to control the aircraft's speed, angle, altitude and other parameters so that the aircraft can climb steadily to the specified altitude.

[0038] (3) Simulated steering: In a virtual environment, the subjects can perform steering operations by controlling the rudder and other flight control systems. They coordinate the aircraft's body attitude and flight direction to ensure that the aircraft remains stable during the steering process.

[0039] (4) Simulated level flight: Level flight is a state in which the aircraft maintains a stable flight. The test subjects maintain the stable flight of the aircraft at a specified altitude and speed and master the flying skills and flight management skills required for level flight.

[0040] (5) Simulated descent: In a virtual environment, the subjects gradually lower the flight altitude in preparation for landing. During this process, the subjects need to control the aircraft's descent angle, speed, and attitude to ensure that the aircraft can land safely and smoothly.

[0041] (6) Simulated landing: In virtual reality training, the subjects practice basic landing skills and procedures to improve their landing ability. This includes mastering how to align with the runway, control speed and altitude, etc. Through repeated training, the subjects can gradually master the key elements of landing and improve their accuracy and stability in actual operations. During the flight, a wingman appears, flies in a fixed posture, and adjusts the flight speed according to the current user's flight status (direction is fixed).

[0042] 2. Scene module:

[0043] (1) Mountain scene: The low-altitude mountainous terrain is complex and high in altitude. Low-altitude flight reference objects are relatively obvious, and there is no airport setting.

[0044] (2) Plain scene: The terrain in the plain area is relatively flat, the requirements for flight operations are relatively low, the visual reference objects are relatively simple, and an airport is set up, including airport buildings and other contents, which are mainly used for takeoff and landing.

[0045] (3) Snowy mountain scene: The snowy mountain environment is harsh, the field of vision is limited, the ground signs are not obvious, the reflection under light is serious, there are many reference objects, and there is no airport.

[0046] (4) Ocean scene: simulates the ocean scene, including the reflection of the ocean when illuminated, and ships in the ocean as reference objects.

[0047] 3. Climate module (cloudy, foggy, thunderstorm) time of day scene (dusk (dawn), day, night).

[0048] (1) Climate: Climate conditions have a significant impact on flight. The climate scenes are mainly set to four types of climate, including sunny, cloudy, overcast and foggy. On sunny days, visibility is good, with no clouds in the sky; on cloudy days, visibility is good, with more clouds, and simulated flight can penetrate thick clouds; on cloudy days, visibility begins to decrease; on foggy days, visibility is extremely poor, and it is easy to have a flight illusion. The four types of climate scenes can be set as fixed climates, or they can be set to switch automatically and randomly over time.

[0049] (2) Time of day: Light conditions vary at different times of day, which has a great impact on the pilot's spatial perception. Strong light during the day may cause temporary blindness to the pilot; during night flights, visibility is reduced and the pilot must rely on instruments to fly; at dusk, light changes rapidly, placing higher demands on the pilot's adaptability and concentration. In plain scenes, because there are airport take-off and landing missions, the lights at the airport can be used as a guide.

[0050] Because various scenes are developed with separate scene maps and special effects, switching needs to be done through the system's UI main interface.

[0051] 4. Can record flight trajectory and complete time module

[0052] The flight record parameters that can be provided for development are:

[0053] (1) Flight time: timestamp of the current flight time, flight completion time, etc. You can set the absolute time or the current simulation time.

[0054] (2) Flight coordinate trajectory: x, y, and z axis coordinate data.

[0055] (3) Flight speed: record the flight speed data at each time.

[0056] The above data can eventually be exported into a data table through the system background.

[0057] 5. Visual quality improvements for builds using VR

[0058] Use the VR simulation experience function to create a visual experience animation scene that simulates the focusing function of the human eye, and adjust the focus of the picture repeatedly. The position of the subject in the picture cannot be moved, but the viewing angle can be adjusted freely.

[0059] Due to the freedom characteristics of VR, it is impossible to determine the visual point of the subject's focus through the VR device, so a three-dimensional natural scenery animation with a fixed perspective alternating between near and far is made to guide the subjects to watch. The animation time does not exceed 30 seconds.

[0060] 2. Implementation of required technologies

[0061] 1. Flight simulation technology

[0062] It mainly provides the pilots in training with a realistic sense of flight control force and flight status changes. The pilots judge the flight status and perform corresponding operations based on the changes in the sense of control force. The fidelity of force simulation is an important criterion for evaluating the level of flight simulation, and requires the control load system to have good simulation fidelity for static and dynamic control force. The control load system of the flight simulator is divided into two parts: the main control load system and the auxiliary control load system: the main control load system is used to simulate the lateral and longitudinal control stick force and pedal force and generate rudder angle signals, and the force fidelity requirements are relatively high; the auxiliary control load system is used to simulate the control force of the throttle lever, front wheel turning, brake and other control systems, and the force simulation fidelity requirements are low.

[0063] The flight simulator instrument system provides the pilot with information such as the aircraft's altitude, airspeed, vertical speed, heading and attitude, creating an instrument environment for the pilot that is the same as a real aircraft, thereby simulating the aircraft's flight environment in conjunction with the visual simulation system. The pilot uses the instrument system to dispatch air-to-ground traffic.

[0064] 2. Virtual Reality

[0065] The military pilot psychological stress training system based on virtual reality technology is a combination of 3D modeling and virtual reality VR technology. The main development language used is C++, and the development software for scene applications and interactive systems is Unreal Engine 5 (UE5). With professional equipment and the application of the UE5 engine development system, we can fully realize the immersive experience of aviation flight that we want.

[0066] Build a scene: Create a visual, interactive, script-driven virtual reality environment.

[0067] Stereoscopic rendering: Use two cameras to render the scene, representing the user's left and right eyes respectively, and then through the head display lens, the two pictures are overlapped to form a clear scene with depth vision. Real-time rendering is achieved through the UE5 engine, which is used to quickly build VR content flight simulation scenes and interactive processes.

[0068] Head tracking: Capturing the position and rotation of the headset to change the position and rotation of the camera in the virtual world.

[0069] Polarized 3D imaging: Polarized imaging is to send two images with different polarization states to both eyes, and each eye is only allowed to see one of them. Using UE5 to create 3D virtual reality content is to create these two images and project them to both eyes.

[0070] 3. Visual simulation technology

[0071] It is mainly composed of a visual generation system and a display system, which generates a view outside the cockpit for the pilot and describes the geometric shapes, relative positions and motion relationships of various entities in the scene. The visual display is mainly a virtual reality helmet display, which can achieve a more realistic immersive feeling.

[0072] This project requires a lot of model building for visual simulation. For flight simulators, large terrain modeling and scene construction are crucial. Simulation environment production includes: model design, scene construction, texture design and production, special effects design, etc.

[0073] Visual simulation requires the construction of environmental special effects. It is essential to build weather, waves, ships, and weapon launch contrails in a virtual battlefield environment. For example, weather special effects can be constructed through particle special effects technology, clouds of various shapes and properties can be constructed using volumetric cloud technology, and rivers and lakes can be constructed using fluid technology.

[0074] 4. Flight motion collision technology

[0075] The efficiency of the collision detection algorithm directly affects the real-time performance of various applications, especially in large scenes. Since there are many objects and moving objects in the surrounding scenes, it is necessary to repeatedly perform collision detection between a large number of objects. A fast collision detection algorithm is a very important key technology to realize such applications.

[0076] Since there are bound to be collision problems in actual aircraft flights, it is inevitable to add collision detection functions in virtual reality simulation systems to avoid abnormal situations such as aircraft flying through terrain in virtual environments, making the virtual reality system more realistic.

[0077] 6. Flight simulation review technology

[0078] After the simulated air team completes the mission, the system records the real-time flight data of each unit and presents it in two-dimensional and three-dimensional forms. During the simulation process, the numerical visualization simulation module generates aircraft motion data, including aircraft orientation, speed, overload, spatial position and other data, which are played back in real time in a two-dimensional situation. By reading the flight parameter record data, the real-time flight trajectory in the simulation environment is simulated, and the simulation process and real flight parameter data are displayed in real time in the form of realistic three-dimensional animation for pilots to review, demonstrate and analyze.

[0079] 3. System Implementation Plan

[0080] 1. The first step is to evaluate the visual impact direction and technical requirements

[0081] While satisfying the test personnel's flight under different environmental conditions, it can also cause visual impacts close to the real environment on the test personnel's eyes. It can also meet the evaluation and comparison of the pilot's visual quality under simulated eye conditions, so as to better collect optical quality evaluation indicators such as high-order aberrations, low-order aberrations, contrast sensitivity, intraocular scattering index, accommodation power, and refractive power.

[0082] The specific implementation is based on the multi-light source simulation rendering function of Unreal 5, using parallel light and point light mixed rendering, and superimposing exponential fog and particle cloud to further refract or scatter the light source. After simulating the complex light source of the real environment, the reflection field box is superimposed again to further increase the complexity of the light source direction in the environment. A numerical modification interface is left in the scene to facilitate correction after inviting pilots to collect environmental data.

[0083] 2. The second step is realistic high-precision modeling

[0084] To further achieve a more realistic test environment, the simulation of the 3D models in the scene uses high-definition textures to complete the main 3D models (mainly including: aircraft, cockpit, buildings, etc.). The aircraft model realizes the movable parts of the wings, tail, landing gear, etc. to improve the authenticity of the fighter, and the cockpit provides synchronous movement of the joystick, and provides interface backlight, screen display, cockpit lights, etc. While increasing the authenticity of the tester's experience, it simulates that the pilot will often switch between the cockpit environment (such as: watching the real screen, turning on the fighter panel backlight, turning on the cockpit lights, etc.) and the in-flight environment during the flight mission.

[0085] In order to achieve high-precision models, Maya is used as the basis for modeling and combined with the sculpting software ZBrush to add fine sculpting components to increase the model's fineness. After modeling is completed, it is combined into a high-precision model and imported into Maya for modeling operations. The details on the high-precision model are expanded into a normal map or height map through a ring light source to achieve the fineness of the high-precision model and use a low-polygon model to ensure the smoothness of the software's operations, without too many high-precision models occupying the computing power.

[0086] 3. The third step is to immerse fighter aircraft in operation simulation

[0087] The system makes the flight of the aircraft in VR closer to reality, and realizes the simulated flight feel of the aircraft through the physical formula data code. The aircraft has flight functions such as take-off, left tilt, right tilt, climb, dive, glide, and land, and has simulated aerodynamic data and power system data for the physical formula data code to calculate the flight status of the aircraft and record it. The position of the aircraft in the virtual scene is determined by recording the coordinates of the x-axis, y-axis, and z-axis of the aircraft in the virtual scene, and a continuous flight trajectory is formed by continuously positioning the aircraft position in each frame.

[0088] 4. The fourth step is environmental visual simulation

[0089] In order to achieve a higher level of environmental simulation, the system uses satellite map elevation maps, height maps, high-definition satellite photos and other content to build the map when building the entire environment, and uses environmental modules such as particle clouds, exponential fog, ambient light, and shadow rendering in the air to achieve multiple scenes or multiple weather and time effects in the environment.

[0090] Working principle: The utility model is based on virtual reality technology, and utilizes the scene simulation VR glasses body 1 to enable the pilot to perform flight missions in a virtual and changeable environment, and completely simulates all the influencing elements encountered by the pilot in flight. After completing the flight simulation, a simulation scene is provided for the pilot's eye recovery training. When the pilot uses the VR glasses for training, he first loosens the limit bolt 405 outwards to disengage the end of the limit bolt 405 from the first limit hole 402 and the second limit hole 407. At this time, the side wearing strap 401 and the top support strap 406 can be slidably adjusted inside the limit buckle 403 to simulate the scene. The VR glasses body 1 is placed at the pilot's eye position, while the side wearing straps 401 are located on both sides of the pilot's head, and the top support straps 406 are located on the top of the pilot's head. The ends of the side wearing straps 401 and the top support straps 406 are pulled to make the side wearing straps 401 and the top support straps 406 fit tightly with the pilot's head, thereby fixing the scene simulation VR glasses body 1, and then tightening the limiting bolt 405 to make the limiting bolt 405 pass through the first limiting hole 402 and the second limiting hole 407 located inside the limiting buckle 403, so as to limit and fix the side wearing straps 401 and the top support straps 406;

[0091] When the pilot is conducting simulation scene training, the sweat produced by the facial skin will be absorbed by the sweat-absorbing layer 207 made of pure cotton, and cannot pass through the isolation layer 206 to reach the facial fitting silicone pad 205. After the pilot completes the scenario simulation training, the VR glasses wearing component 4 is opened, and the scene simulation VR glasses body 1 is removed. Then, the support plate 201 can be pulled outward. When the support leg 301 moves outward, the limit card block 303 will squeeze the spring 302 back into the inside of the support leg 301. After sliding to the second limit card slot 305, the spring 302 moves upward against the limit card block 303 and is inserted into the inside of the second limit card slot 305. At this time, the support plate 201 and the scene simulation VR glasses body 1 are in a separated state. Each hanging ring 203 is removed from the hook 202, and then the isolation layer 206 and the sweat-absorbing layer 207 can be removed. Then, a new isolation layer 206 and sweat-absorbing layer 207 are replaced, and another pilot can conduct simulation training.

[0092] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
